Control Power Components
There are two configurations in which control power will be distributed
for the drive. The different methods are dependent on what drive option
the customer has chosen:
1. Integrated Line Reactor Drive with Integral Starter (refer to Figure 6.54)
2. Remote Transformer and Starter (refer to Figure 6.55)
3. Integrated Line Reactor Drive with Remote Starter (refer to Figure 6.55)
4. Integrated Transformer Drive (refer to Figure 6.56)
Ride-Through
Standard controls with 5 cycle ride-through – The drive main control
boards will remain energized for a total of 5 cycles after control power is
interrupted. If control power is not restored during the 5 cycles, a
controlled shutdown will occur.
Figure 6.54 illustrates the control power distribution for 6-pulse and PWM
drives with integral starter/line reactor.
